Two of the four cells will contain one recombinant chromosome. In eukaryotic cells, crossing over can also occur during mitosis. Somatic cells (non-sex cells) undergo mitosis to produce two distinct cells with identical genetic material.
Crossing over. Definition. noun. A process occurring during meiosis wherein two chromosomes pair up and exchange segments of their genetic material. Supplement.This occurs at the stage when chromatids of homologous chromosomes pair up during synapsis, forming X-structure (chiasma).rossing over is important because it results in new combinations of genes that are different from either parent, contributing to genetic diversity.
